Air Tightness
While the air receiver tank is pressurized to at least 650 kPa (94 psi) and the
compressor is switched off, listen for any audible air leaks. Squirt soapy water around
any suspect joint and watch for bubbles indicating a leak.
De-pressurize the air receiver tank carefully and all connected air hoses and/or air
piping before commencing any repairs.
Disassemble the leaking joint and clean off all traces of thread tape or sealant using a
wire brush. Apply PTFE thread tape or Loctite™ 243 liquid sealant to the male
threaded connection before reassembling and tightening the joint. Allow approximately
30 minutes for the liquid sealant to cure, if used.
Re-pressurize the air receiver tank and check that the air leak has been rectified before
putting the unit back into normal operation.
Pressure Switch and Pilot Valve
The cut-in and cut-out pressures have been preset at the factory and should not be
altered.
There are no user serviceable parts within these components.
12 Volt Battery
If installed, the factory fitted 12 Volt battery is a maintenance free type.
Ensure correct polarity whenever charging or refitting the battery as described in the
Installation section.
